2D breath-hold phase sensitive inversion recovery (PSIR)
has been shown to provide excellent depiction of myocardial scar and other
clinically relevant conditions. The transition from breath-hold 2D to
respiratory navigator-gated 3D imaging should yield higher SNR and CNR,
allowing whole heart coverage at higher spatial resolution. Current 3D PSIR
implementations navigate only the IR-prepared volume, relying on phase
reference images that may be corrupted by respiratory motion. We hypothesize
that additional navigation of the reference volume will yield more robust
high-resolution imaging. Here, we present an independently-navigated 3D PSIR
sequence and extend its utility to include co-registered T2W imaging volumes.
